hiya guys got my cossie today and its all good bar 1 thing it kangeroos but only when it hits about 1bar???

the engine sounds and runs fine but when its on boost it is fine till it hits about 1bar then it jolts like my fiesta did on overboost???

i thought it could be the overboost or something?? but std small turbo's run 17psi dont they?? which is just over 1 bar,


the car has a K+N, mongoose, d/v, and the injectors are totally blk which is dodgy


basically the car was took in p/x by car craft and i think they have tried to remove some bits to std theres is a bill for

305bhp conversion
hybrid turbo
grp A gasket
mongoose
AP clutch
strut brace


the strut brace has been removed,turbo,exhaust,d/v and gasket are all on but i think the chip has been removed and possibly the injectors sprayed blk or put bak to std....???


can anyone tell me where the ecu is and where the chip should be and how i can tell if its chipped or not??? or if they can shed any light... i think it is overboost tho but just wanna be sure????
